About Overhaul Maintenance

CENTRIFUGAL CHILLERS

Hermetic parts that cannot be disassembled for inspection during regular maintenance (compressor, etc.), require periodic overhaul.
Since centrifugal chillers are rotary machines, the open inspection/servicing of bearings and gears and the measurement of the motor’s electric characteristics are important.
For the restoration of heat exchanger performance, cleaning the inner surface of the tubes with chemicals is also recommended.

ABSORPTION CHILLERS & CHILLER/HEATERS

Aside from proper maintenance, the periodic replacement of consumable components is required to ensure prolonged stable operation.
For absorption chillers and chiller/heaters, the replacement of air-tight packing and valves and the cleaning/inspection of the solution pump and heat exchangers are important.
